"Sancho IV Garc\u00E9s ( 1038 \u2013 4 June 1076), called Sancho of Pe\u00F1al\u00E9n () or Sancho the Noble, was King of Navarre from 1054 to 1076. He was the eldest son and heir of Garc\u00EDa S\u00E1nchez III and Estefan\u00EDa. At the age of fourteen Sancho was proclaimed king in the camp by the field where his father was killed at the Battle of Atapuerca. Sancho's mother served as his regent, remaining faithful to her husband's wishes, she continued the support of the monastery he founded at N\u00E1jera, where several Navarrese monarchs are interred. With his uncle, King Ramiro of Aragon, he forced al-Muqtadir, ruler of Zaragoza, into submission and exacted a tribute. He was in constant conflict with Castile, culminating in the so-called War of the Three Sanchos (1067\u20131068). Years before, Sancho's father had managed to retain a series of frontier lands, including Bureba and Alta Rioja, which had been claimed by Ferdinand I of Castile. Ferdinand's son, Sancho II the Strong sought to reconquer these lands for his kingdom. Faced with an invasion by his cousin the Castilian Sancho, The Navarrese Sancho asked for aid from his other cousin, Sancho of Arag\u00F3n. But their forces were defeated by Sancho the Strong and his trusted alf\u00E9rez (supreme commander) El Cid, Sancho lost Bureba, Alta Rioja, and \u00C1lava to Sancho of Castile. He was assassinated in Pe\u00F1al\u00E9n, whence his nickname, by a conspiracy headed by his brother Ram\u00F3n (el Fratricida, the Fratricide) and his sister Ermesinda. During a scheduled hunt, Sancho was forced from a cliff by his siblings. Upon his assassination, Navarre was invaded and ultimately partitioned between Sancho of Aragon and a third cousin, Alfonso VI of Le\u00F3n and Castile. Alfonso occupied La Rioja and Sancho was proclaimed king in Pamplona."@en . . . . "Sancho IV of Navarre"@en .
